The present invention relates to a bar arrangement inspection device and a bar arrangement inspection method for bar arrangement inspection performed before placing concrete at a construction site.

For example, in order to construct a reinforced concrete structure at a construction site, the reinforcing bars specified in the design are assembled at a predetermined location. Specifically, after assembling reinforcing bars with a diameter specified in the design at a predetermined pitch (hereinafter referred to as reinforcing bars), a formwork is attached to the reinforcing bars, and ready-mixed concrete is cast to form a reinforced concrete structure.

In the reinforced concrete structure constructed in this way, since the reinforcing bars are arranged inside the hardened concrete, the strength of the reinforced concrete is greatly affected, but the reinforcing bar arrangement state cannot be confirmed after construction, and the mold frame. A bar arrangement test is performed to confirm the bar arrangement status before attachment.

Specifically, it is confirmed whether a predetermined number of reinforcing bars having a predetermined diameter are arranged at a predetermined pitch and measured, and the confirmation status and the measurement status are photographed and left as a construction photograph. However, the labor is complicated, and the formwork cannot be assembled until the bar arrangement inspection is completed, so that it is required to be performed promptly.

Therefore, Patent Document 1 proposes a bar arrangement inspection method for determining whether or not the bar arrangement state is correct by photographing the bar arrangement state and measuring the number, diameter, pitch, etc. of the reinforcing bars from the photographed image. ..
However, since the captured image is two-dimensional information, it was not possible to sufficiently inspect the bar arrangement assembled in three dimensions.
